12.1. Startup: ID ISC.ANT.PS-A
Before installing the power splitter you must first tune both antennas. For this the antennas or
gates are connected directly to the Reader. Next tune each basic or basic/complementary antenna
combination (gate) individually.
Once all the antennas are tuned you may install the power splitters.
Each ID ISC.ANT.PS-A was factory tuned and is ready to use as soon as it is installed. To com-
pensate for coupling effects the power splitter may require fine adjustment (see Assembly Guide
for antenna).
If two complementary antennas are connected to the ID ISC.ANT.PS-A you may use Jumpers JP1
and JP2 to bridge the galvanic isolation between the Reader and the antennas. This reduces the
signal losses by approx. 1-2 dB..
